COMBINED SHADE AND POLE BRACKET.

Specification of Letters Patent.

Application filed. October 25, 1909.

Serial No. 524,300.

To all whom it may concern:

Be it known that I, NEHEMIAH B. CRosBY, a citizen of the United States,residing at Bridgeport, county of Fairfield, State of Connecticut, haveinvented Improvements in Combined Shade and Pole Brackets, of which thefollowing is a specification.

This invention has for its object to provide a shade and pole bracketwhich may be secured to window casings without the use of screws andwithout marring the casings, which may be placed on either side of thecasing and may be readily removed, replaced or transferred and whichshall be adjustable to provide for varying widths of shades.

With these and other objects in view I have devised the novel bracket ofwhich the following description in connection with the accompanyingdrawings is a specification, reference characters being used to indicatethe several parts.

Figure l is a front elevation showing my novel bracket secured to awindow casing as in use, a curtain pole and shade being indicated bydotted lines; Fig. 2 a side elevation corresponding therewith; Fig. 3 asimilar view showing the shade and pole brackets reversed as when usedfor inside shades and hangings; Fig. 4: a rear view of the bracketdetached; Fig. 5 a section on the line 55 in Fig. t; Fig. 6 an elevationillustrating a form adapted for pole brackets only; Fig. 7 a verticallongitudinal section of Fig. 6; Fig. 8 an elevation illustrating a formadapted for inside shades only; and Fig. 9 is a vertical longitudinalsectional view of Fig. 8.

1O denotes a window casing, 11 (see dotted lines) a curtain pole and 12(see dotted lines) a shade.

The essential feature of the invention is that the base plate 13 isattached to the casing by a fixed, inwardly-facing L-shaped prong,indicated by 14, and a movable inwardly-facing L-shaped prong, indicatedby 15, and that a cam 16 is provided on the face of the plate forforcing the movable prong toward the other prong, thus causing them togrip the wood of the casing firmly and lock the base plate securely inplace.

The simplest application of the invention is the form illustrated inFigs. 8 and 9, which is especially adapted for inner shades, so called;that is for shades secured within and operating within the casing asdistinguished from outer shades, so called, which are secured to theouter face of the casing. In Figs. 8 and 9, fixed prong 14: is placed atthe upper end of the base plate and the cam is pivoted at the lower endthereof, the cam being in all cases provided with a handle 17 forconvenience in operation. 18 denotes a shade bracket which is L-shapedand is shown as adjustably secured to the head 20 of a slide 19 by meansof a set screw 21 which passes through a slot 22 in the head and engagesthe base plate of said shade bracket. The slide is retained in place byguides 23 upon the base plate and carries the movable prong 15 whichextends through a slot 24 in the base plate. The cam bears against thelower end of the slide and is adapted to force it upward driving themovable L-shaped prong forward, and also moving the base plate downwardslightly so that both prongs are forced into the wood of the casing,locking the base plate securely in place. In detaching the base platethe cam is of course turned backward to the position indicated by dottedlines in Fig. 8 leaving its short diameter in alinement with the slidewhich drops down. The base plate is placed in position on the casing,the prongs driven into it by a slight blow and then the cam is turned tothe full line position in Fig. 8, which looks the base plate securely inplace. The shade bracket may be adjusted inward or outward to compensatefor variation in the width of shades by loosening set screw 21 andmoving the bracket inward or outward as may be required and then lookingit in place by tightenting up the set screw.

The form illustrated in Figs. 1 to 5 inclusive is adapted to carryeither an outside or inside shade, also a curtain pole. The fixed prongis located near the lower end of the base plate and the cam at the upperend. 25 denotes the shade bracket which is L- shaped as before andslides transversely in guides 26 at the lower end of the base plate tocompensate for varying widths of shades. In case an inside shade 1srequired with a base plate upon the outer face of the casing it issimply required to reverse the bracket, that is change it from theposition shown in Figs. 1 and 2 to the position shown in Fig. 3. Thebracket is locked in position after adjustment by means of a set screw27 which engages the base plate and the head of which engages thebracket. 28 denotes a pole bracket which slides transversely in guides29 at the upper end of the base plate. The pole bracket may be reversed,as shown in Fig. 3. The movable prong in this form is carried by a slide30 which passes under the pole bracket and between the guides, the prongextending through a slot 31 in the base plate. The bracket is locked inposition after adjustment by means of a set screw 32 in the slide, thepoint of which bears against the base plate and raises the slidetherefrom when the set screw is turned inward, clamping the pole bracketin the guides, as clearly shown in Fig. 5. In this form the cam bearsagainst the upper end of the slide. In attaching the bracket the cam isturned backward, set screw 32 loosened, the slide raised and the prongsdriven into the wood of the casing as before, after which the cam isturned to the locking position as in Fig. 1, which forces the slidedownward, drives the movable prong into the wood and also raises thebase plate slightly so that both prongs are locked in the wood asbefore.

The form illustrated in Figs. 6 and 7 differs from the other forms indetails only. The slide, indicated by 33, has no function other thancarrying the movable prong. It is retained in place'by a guide 34 andthe prong extends through a slot 35 in the base plate, the fixed prongbeing at the upper end of the base plate as in Figs. 8 and 9. Near theupper end of the base plate is an oscillating pole bracket 36 carried bya plate 37 which 1s pivoted to the face plate as at 38. The lower end ofplate 37 is an arc of a circle of which the pivot is the center. Polebracket 36 is locked in position by a washer 39 carried by a thumb screw40 which passes through another washer 4:1 and engages the face plate.Stops 42 at the ends of the arc engage washer 4:1 and limit theoscillation of plate 37. In putting in a pole, thumb screw 40 isloosened and the bracket swung into position to receive the end of thepole,-as indicated by dotted lines. The bracket with the pole therein(there being of course a similar bracket on the other side of thecasing) is then swung to place and locked there by tightening up the setscrew, as-shown in Figs. 5 and 6.

It will-of course be obvious that the shade and pole brackets in theseveral forms may be adjusted and'in the form illustrated in Figs. 1 to5 inclusive may be reversed without loosening the base plate.

Having thus described my invention I claim:
